Dynamic parameters of dividing L. pictus eggs

Measurement	Control	HG	Taxol	Urethane
Polar anaphase astral MT growth rate (μm/min)	10 ± 2	8.2 ± 2	na*	na*
Equatorial anaphase astral MT growth rate (μm/min)	8.3 ± 2	8.0 ± 2	na*	na*
Rate of anaphase chromosome segregation (μm/min)	4.0 ± 0.5	4.0 ± 1	3.7 +/- 1	4.2 ± 0.5
Rate of furrow ingression (μm/min)	15 ± 2	12 ± 1	10 ± 5	na*
Time from anaphase onset to furrow initiation (min)	13 ± 0.5	9.5 ± 1	na*	na*

All measurements were made on time-lapse stacks of either GFP-EB1-microinjected or Hoechst-stained cells, acquired using either Leica or MetaMorph imaging software. Each measurement represents the mean value obtained from at least five independent measurements. ± represents the range of data.

^*na indicates either that we were unable to make accurate measurements of the dynamic parameter being assessed or that the parameter was not relevant under the condition being tested.
